2013 poured into a snifter. Dark as night with minimal dark brown head which quickly disappears. I think I can taste bitter, semi-sweet chocolate paired with a roasty coffee-filled linger. The bitterness, to me, is from the chocolate, I don't necessarily pick that up from the coffee influence. Dark brown sugar, too, and does sweeten up a tad as it warms. Drinks very smoothly for 11.0% but even after it warmed I couldn't help but notice the lingering bitterness. Tends to be a bit of a downgrade for me.
